The device isshort-circuit protected and the internal frequencycompensation ensures stability without externalcomponents. A low value potentiometer may beconnected between the offset null inputs to nullout the offset voltage as shown in Figure 2.The µA741C is characterized for operation from0°C to 70°C. The µA741I is characterized foroperation from –40°C to 85°C.The µA741M ischaracterized for operation over the full militarytemperature range of –55°C to 125°C.symbolIN +IN –OUT+–OFFSET N1OFFSET N2Copyright © 2000, Texas Instruments IncorporatedPRODUCTION DATA information is current as of publication date.Products conform to specifications per the terms of Texas Instrumentsstandard warranty.

These are stress ratings only, andfunctional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is notimplied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.NOTES: 1. All voltage values, unless otherwise noted, are with respect to the midpoint between VCC+ and VCC–.2. Differential voltages are at IN+ with respect to IN–.3. The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 V, whichever is less.4. The output may be shorted to ground or either power supply. For the µA741M only, the unlimited duration of the short circuit appliesat (or below) 125°C case temperature or 75°C free-air temperature.DISSIPATION RATING TABLEPACKAGETA ≤ 25°CPOWER RATINGDERATINGFACTORDERATEABOVE TATA = 70°CPOWER RATINGTA = 85°CPOWER RATINGTA = 125°CPOWER RATINGD 500 mW 5.8 mW/°C 64°C 464 mW 377 mW N/AFK 500 mW 11.0 mW/°C 105°C 500 mW 500 mW 275 mWJ 500 mW 11.0 mW/°C 105°C 500 mW 500 mW 275 mWJG 500 mW 8.4 mW/°C 90°C 500 mW 500 mW 210 mWP 500 mW N/A N/A 500 mW 500 mW N/APW 525 mW 4.2 mW/°C 25°C 336 mW N/A N/AU 500 mW 5.4 mW/°C 57°C 432 mW 351 mW 135 mW
